In two freshman residence halls at Susquehanna University, Selinsgrove, Pa., all former coin-operated laundry machines have been converted to eSuds, a coin-free system that allows students to swipe their ID cards, or debit/credit cards, to do their laundry.

When eSuds, provided by USA Technologies, was first installed all old machines had to be replaced with newer models that could handle the new technology. There is also a Web site where a student can go to check laundry machine availability and have an email sent when a washing machine or dryer becomes available.
